To all whom it may concern.-

Be it known that I, DRUITT HALPIN,a subjectof the Queen of Great Britainand Ireland, residing at Victoria Chambers, in the city of ,VVestminsteKingdom of Great Britain and Ireland, have invented new and useful Meansfor Supplying Water to Marine-Engines in Steamships or Vessels, (forwhich I have obtained patents iin Great Britain, No. 3,251,bearingdateJuly 25,1881; France, No. 145,311, bearingdate September15,1881; Belgium, No.

55,795 B, bearing date September, 1881, and

Germany, No. 12,348, bearing date January 27, 1880,) of which thefollowingis a specification.

For drawingthe required supplies for marineengines from the externalwater the side of the vessel is usually pierced below the Water-linewith holes provided with cocks or valves. 1n case of fracture orderangementof these cocks `or valves, or of their becoming detached fromthe vessels side, there is greatdanger of flooding the vessel, and it isdifficult to repair or replace such fittings without incurring expenseand delay in docking the vessel.

My invention relates to means of avoiding these evils, which I effectinthe following manner: Within thevessel, close at the side thereof, Iform a water-tight Siphon-chamber, extending from below the water-lineup some dis tance above the water-line, and I divide this chamberintotwo channels by a vertical partition extending from the bottom nearly tothe top thereof. At lthe bottom of one of these channels Imake anapertureor apertures to the external water, and at or near the bottom ofi the other channel I make all the necessary aper tures with their cocksor valves for the several waterlsupplies. Thus the external water has nodirect passage to theinterior of the vessel, but has to ascend the onechannel of the siphon-chamber to a level above the water-line, andpassing over the partitiondescends the other channel to give therequired supplies. At the top of the Siphon-chamber Ifprovide a cock orvalve, which can be opened to admit air so as to prevent siphon actionin the chamber. Thus, if any of the cocks, valves, or pipes within thevessel should become fractured or deranged, the communication with theexternal water can be entirely cutoff by opening the air cock or valve,and the fractured `or deranged part can be repaired Without thenecessity for docking. In cases where the internal connec- `tions to thechamber require supply before the engines are started the chamber may bepro vided at the top with an ejector-pump or other exhauster solas towithdraw the air from the chamber and charge it from outside with waterready for the supply of these connections, theV blow-off water may bedischarged through the Siphon-chamber, the blow-off valve or cock beingfor this purpose fitted along with the su pply valves or cocks to thewall ofthe siphonchamber. The siphon-chambermay lbeformed in variousways so as to suit the structure of the vessel or the position which itmay most conveniently occupy.

Referring to the accompanying drawings, Figure 1 is a part transversesection of a vessel at the enginerooin. Fig; 2 is apart elevation of theside; and Fig. 3 is a sectional plan on a a, Fig. 1. Y

I have assumed that in this oase each frame of the vessel consists of apair of augle-irons placed back to back. Between these angleirons Iintroduce plates, projecting inward, to form the sides and partition ofthe Siphon-chamber, divided into its two channels, d and e, which Icover by plates secured to angle-irons, riveted to the projectingplates. The middle partition stops short of the top of the chambersuflciently far to give free passage for water from the ascendingchannel d to the descending channel e. Openingso c, which may begrated,are made through the ships side at or near the bottom ofthe channel d,and a suitable communicatiomf, with its necessary valves, is made fromthe bottom ofthe channel c to the condenser and feed-pump or other placerequiring water-supply. By opening an air-cock, r, situated near the topofthe chamber, its action as a Siphon can, when required, be arrested.The siphon action may be started by means of a steam-ejector, h,exhausting the air by a pipe,

g, which is lcd up within the chamber nearly IOO from commuuicationwiththe ejector and condenser, or with either. The ejector h may be employedto create a partial vacuum in the condenser to aid in starting theengines. The steam for working the ejector may be taken from thev mainboilers or the donkey-boiler by either branch ov or p of the steam-pipen. It is obvious that, instead ofan ejector, an air-pump or otherexhauster may be employed for the purpose'of charging the Siphon, or thesiphon may, in the rst place, have its air and water ejected byintrodncing a current of steam, by the subsequent condensation of whicha vacuous condition will be produced, causing` the water to ascend thechannel d so as to charge the siphon. The discharge from the condenseris delivered in the usual wayby the pipe q, having its external openingabove the waterline. As shown in Fig. 4, the ascending channel, d, maybe formed, as described, between a pair of the frames of the vessel, thedescending channel, e, being a pipe attached to the upper end of d. Asshown in Fig. 5, and in the sectional plan, Fig. 6, the channels may beformed in the angle where a bulk-head meets the side of the vessel, ortwo' pipes, d and e, may be employed to constitute the siphon, as

shown in Fig. 7. .When the construction of the channels is modified, asshown in Figs. 4, 5, 6, and 7, or otherwise, the air-cock and ejectorcany be applied to them as described with reference to Figs. 1, 2, and.3.`

What I claim is- A steamshipor vessel, in which supplies for the enginesare drawn from the external water, provided with a separate lWater-tightsiphonchamber located within and close to one side of the vessel, andextending from below the water-line to a point above the water-line,saidchamber being provided with two channels divided by a verticalpartition,one, the ascending channel, communicating with the exterior ofthe vesselbelow the water-line, and theother,

,the descending channel, communicating with the interior of the vessel,whereby a direct opening through the side of the ship or vessel belowthe water-line for the supply of' water is avoided, in combination withsuitable means for charging or discharging said channel, substantiallyas described.
